Description
Technical Field
The invention belongs to the field of air compressors, and particularly relates to an air compressor modified based on a diesel engine.
Background
An air compressor (hereinafter referred to as an air compressor) is an important energy generation form in the prior art, and compresses air through reciprocating motion of a piston in a cylinder body to generate high-pressure gas, so that the air compressor is widely applied to various links of life and production, such as various industrial fields of machinery, metallurgy, electronic power, medicine, packaging, chemical industry, food, mining, textile, transportation and the like, and the air compressor is required to be used for production. At present, common air compressors in China market protect reciprocating air compressors and screw air compressors, and some industries apply to imported air compressors for production.
The diesel engine is a mature technology at present and comprises cylinder blocks (6 cylinders and 4 cylinders are generally available in the prior art), each cylinder block is provided with an air inlet and an air outlet, all the air inlets are connected with air inlet pipelines through inlet valves, and the air outlets are connected with all air outlet pipelines through exhaust valves. Be equipped with the piston in the cylinder block, the piston passes through the connecting rod that crankshaft drive and piston link to each other up-and-down reciprocating motion in the cylinder block, and the bent axle drives the camshaft motion simultaneously, and then the camshaft controls opening and closing of the (air) intake valve of every cylinder block and gas outlet respectively, and concrete process is: when the piston starts to move from the top dead center to the bottom dead center, the crankshaft drives the camshaft through the intermediate gear to open an intake valve of the cylinder block, and when the piston moves to the bottom dead center, the camshaft controls the intake valve of each cylinder to close; then the crankshaft continues to drive the piston to operate to compress gas from the lower dead point to the upper dead point, when the piston operates to the upper dead point, the fuel oil sprayed by the fuel injection nozzle is combusted to apply work to the outside, the original air is consumed, because the gas pressure and the temperature are increased rapidly during combustion, the piston operates from the upper dead point to the lower dead point under the action of the gas pressure, and when the piston operates to the lower dead point, the camshaft drives the crankshaft to open the exhaust valve; and finally, the piston moves from the bottom dead center to the top dead center under the driving of the crankshaft, the burnt waste gas is discharged, when the piston moves to the top dead center, the exhaust valve is closed, the intake valve is opened, and the process is repeated again. In order to achieve the above working principle, the transmission ratio of the crankshaft gear to the camshaft gear in the prior art is 2:1, the radius of the cam shaft gear is twice larger than that of the crank shaft gear, and the opening difference between the air inlet and the air outlet is 360 degrees.
As can be seen from the above description, both the air compressor and the diesel engine perform the corresponding functions by the principle of compressing air through the reciprocating motion of the piston, but due to the difference in the development processes between the diesel engine and the air compressor, the technology of the diesel engine has been mature up to now, the price of the diesel engine is relatively low, and the applied components are not only very easy to purchase, but also relatively low, so that the air compressor has the following defects:
(1) the pressure is little during operation: the maximum pressure of the existing large-scale air compressor during working can reach 8 pressures, and the pressure value of the existing large-scale air compressor is still small for the manufacturing industry, so that the production requirement cannot be met;
(2) the cost is high: because the air compressor needs to output high-pressure gas, the requirements for each part of the air compressor are higher, namely the manufacturing cost of the air compressor is higher, and the price of the air compressor is higher when the air compressor is purchased by a corresponding user;
(3) later maintenance costs are more: because the manufacturing models of the air compressors are not uniform and the air compressors are manufactured according to actual needs of customers, parts of the air compressors in different fields cannot be used universally, so that the corresponding accessories are not easy to purchase in the market after the air compressors are broken down, even if the air compressors can be purchased, the requirements on the air compressors are high, and the requirements on the corresponding accessories are also high, so that the later maintenance cost is high, particularly, the imported air compressors are difficult to purchase in the market once the air compressors are broken down and the parts need to be replaced, and the price is correspondingly high even if the imported air compressors are purchased;
(4) the manufacturing precision is relatively low: because the development of the air compressor is relatively lagged behind that of the diesel engine, people can study the diesel engine more deeply, so that the development of the existing diesel engine is more mature than that of the air compressor, the precision is relatively high, the price is relatively low, the manufacturing precision of the corresponding air compressor is relatively too low, once unqualified products are met, serious accidents can be caused, the production of enterprises is influenced, and the personal safety of workers is seriously threatened.
